Bodyguard 2 device has an in-built USB plug so it doesn't need any charging cables. When the device's battery is running low during the measurement it signals this with an orange light, see more info about the lights from here.


  1. Gently remove the cable of the device by pulling on the connector to expose the USB plug.
  2. Plug the device into the USB port of your computer to charge. 
  3. Wait for the device to charge. A blinking orange light indicates that device is charging. When the device is fully charged, the light will stop blinking and remain lit continuously. It may take 1-2 hours to fully charge the device.
  4. Reattach the cable. Make sure you attach the cable in the right way. The connector should fit securely with the device, and the stickers should be on the same side.
